Abstract
A flame attenuation apparatus for forming flame attenuated fibers, preferably glass fibers, includes means for providing continuous filaments; burner means for providing a high temperature, high energy stream of combustion gases; means for feeding the continuous filaments into the high temperature, high energy stream of combustion gases; and an elongated rod filament guide with a plurality of grooves therein for receiving, guiding and supporting the continuous filaments, as the continuous filaments are fed into the high temperature, high energy stream of combustion gases. The elongated rod is preferably made from graphite with a boron-nitride coating and, preferably, has at least two flat surfaces and at least two curved surfaces with the grooves therein.
